Point type flame detector method based on detection of hydrogen-containing and carbon-free compound

The invention discloses a point type flame detector method based on detection of a hydrogen-containing and carbon-free compound, and belongs to the field of fire alarm. A pyroelectric sensor with a broadband wavelength of 2-3 [mu] m and an ultraviolet photosensitive tube are adopted to carry out a logic algorithm to realize combustion fire detection of a hydrogen-containing and carbon-free compound in the air or a pyroelectric sensor with a wavelength of 2.86 [mu] m +/-0.2 [mu] m, a wavelength of 2.7 [mu] m +/-0.2 [mu] m, a wavelength of 3.8 [mu] m +/-0.2 [mu] m, a wavelength of 3.6 [mu] m +/-0.2 [mu] m and a wavelength of The pyroelectric tube and the ultraviolet photosensitive tube with four wavelengths of 4.4 [mu] m +/-0.2 [mu] m carry out a logical algorithm to realize combustion fire detection of a carbon-free compound containing a hydrogen element in the air. In order to solve the problem that fire disasters containing hydrogen elements and carbon-free compounds cannot be effectively detected by a tradi
